This invention relates to a smoke-disposal and draft-inclucing apparatus for locomotives of the type utilized in round-houses for conducting the products of combustion s'from the stacks of, and for inducing draft in the furnaces of, locomotives.

The broad object of the invention is to provide an apparatus of the character mentioned in which will be incorporated various novel and improved features and character- 1 istics of construction designed to render the present apparatus an improvement generally over more or less similar apparatuses l1eretofore known. 1 More specific objects are to equip the uptake pipe of the apparatus with a cover adapted to be closed at all times whenflthe apparatus is out of use and-adapted to be open atall times when a locomotive smoke stack is situated in operativeposition relatively to the apparatus; to equip the apparatus with a valve adapted to close up the passage through the up-take pipe or conduit and open an exhaust passage leading from a locomotive fire box when the exhauster of the apparatus is caused to function, and to open up the passage through said up-take pipe or conduit and close said exhaust passage when said exhauster is not 39 functioning; to equip the apparatus with a raising and lowering mechanism adapted to be actuated by the smoke stack of a l0comotive to associate the'up-take pipe of the apparatus with, and to remove "said up-take pipe from, said smoke stack; to provlde 1n the apparatus an arrangement adapted to care for variationsin the heights of locomotive smoke stacks, as well as variations from the vertical as may be caused, for ex- 49 ample, by a broken spring; to provide in the apparatus an arrangement permittlng a locomotive smoke stack to'bein communication with the up-take pipe of said apparatus at variablelocation in the vicinity of the apparatus, thus making it possible to move a locomotive backwardly or forwardly within limits while being fired, or while a fire exists in the fire box, without emitting smoke or gases into a 'roundhouse; andto equip the telescoping barrels of the up-take pipe with mechanism adapted to prevent binding, as might overwise be caused when the pull of the counterweight and the lifting movement of a locomotive smoke stack upon a telescoping barrel are unequal.

Other objects and advantages of the invention will become apparent from the'full description thereof now to be made, it being understood that the disclosure herein is merely illustrative and intended in no way in a limiting sense, changes in details of construction and arrangement of parts being permissible so long as within the spirit of the invention and the scope of the claims which follow.

With respect to the drawings and the numerals of reference thereon, 10 designates the roof of a round-house which may have engine stalls in any desired number, 11 represents columns between the stalls, and 12 indicates a locomotive upon a track 13 and within a stall.

A separate smoke-disposal and draft inducing apparatus, denoted generally at 14, ma be provided for each stall.

n up-take pipe or conduit 15 of the apparatus 14 may consist of an upper barrel 16, suitably supported upon the round-house roof, as by a closure hood 17 surrounding said barrel 16 and an opening 18 in said roof through which the lower end portion of the barrel 16 projects, an intermediate barrel 19 having its upper end portion pivotally supported upon the lower end portion of the barrel 16, as at 20, and a lower barrel 21 having its upper end portion telescopingly received in the lower end portion of the barrel 19, as at 22.

The pivotal arrangement between the upper barrel 16 and the intermediate barrel 19 is such that the barrels 19 and 21 can swing asa unit longitudinally of the track 13, and the barrel 19 includes elongated slots 23 in its opposite walls receiving the pivot pin 20 to allow for slight sidewise swinging movement of the intermediate and lower barrels, as, for example, to accommodate the lower barrel 21 to a locomotive smoke stack which may not be exactly vertical, as will be understood. A packing 24 for the joint between the upper barrel 16 and the intermediate barrel 19 may be of any preferred design and construction.

A counterweight 25, suspended from a cord 26 which rides over fixed pulleys 27 and is attached to the barrel 21 as at 28, is for'the purpose of counterbalancing the lower barrel, and the telescoping barrels are equipped with mechanism adapted to prevent binding which might otherwise be caused when the pull of thecounterweight and the lifting movement of a locomotive stack upon the lower telescoping barrel are unequal. As disclosed, guide slats 29 are secured upon the outer surface of the barrel 21 in diametrically opposed relation to each other, the said guide slats extending length- Wise of said barrel 21 and preferably lying in a lane which extends substantially longitudinally of the track 13, and brackets 30, secured upon the barrel 16 as at 31, support guide rollers 32, two for each guide slat, having flanges 33, which pass through openings in the barrel 19 and engage the opposite sides of said guide slats, the said guide rollers being mounted in said brackets as denoted at 34. A packing 35 between the intermediate barrel 19 and the lower barrel 21 may be of any preferred design and construction.

A raising and lowering mechanism of the apparatus, represented generally at 36, is adapted to be actuated by the smoke stack of a locomotive to associate the up-take pipe or conduit 15 with said smoke stack and to remove said up-take pipe or conduit from the smoke stack. Of said raising and lowering mechanism, 37 designates spaced apart suspension slabs upon the round-house structure suitably supporting upper and lower, horizontal cross shafts, indicated 38 and 39, respectively, and 40 denotes a raising and lowering bar extending substantially longitudinally of the track 13, the rearward end portion of said bar 40 being freely received between said suspension slabs and said horizontal cross shafts in such manner that the bar can have upward and downward swinging movement, as well as longitudinal sliding movement, but can have very little lateral or sidewise movement, and the forward end portion of said bar 40 being pivotally attached inany convenient manner, as at 41, to the belled, coneshape, or funnel-shape mouth 42 of the lower barrel 21, so that the said bar 40 is normally suspended from said lower barrel.

Means for adjustably limiting downward movement of the lower barrel 21 in the intermediate barrel 19 may consist of rods 43 suitably secured to the mouth of said barrel 21, as at 44, assing upwardly through ears 45 upon a ange 46 set at the lower end of the barrel 19, and carrying nuts or collars 47 situated to engage the upper surfaces of said ears, each said nut or collar receiving a set screw 48 for locking the same at any preferred location along the length of the corresponding rod.

A counterweight 49, suspended from a cord 50 which rides over fixed pulleys 51 and is attached to the bar 40 as at 52, is for the purposes of counterbalancing said bar 40, and of normally situating sald bar and the up-take pipe at about the dotted line position disclosed in Fig. 1.

A cover 53 for the upper end of the uptake pipe or conduit is adapted to be closed at all times when the apparatus is out of use and is adapted to be open at all times when a locomotive smoke stack is situated in operative position relatively to the apparatus. As disclosed, the cover 53 is pivoted upon the upper portion of the barrel 16 as at 54, and includes a protruding arm 55 carrying' a weight 56 of suflicient magnitude to move said cover to open position. A cord or wire 57' attached to the cover at the side of its pivot opposite the weight is also attached to the end portion of the cord 26 which is adjacent the barrel 21, the arrange ment being such that when the said barrel 21 is moved to its lowermost position by its own weight and the weight otthe bar 410, the cord or wire 57 is drawn downward 1y to move the cover to closed position against the action of the weight 56, but when the barrel 21 is elevated, said weight acts to open thecover. Means may be provided for closing the cover even when a smoke stack is associated with the up-takeconduit.

An exhauster for the up-take pipe 15 may consist of a usual or preferred type of fan 58 actuated by a suitable motor 59, both shown situated upon the round-house roof. As disclosed, the upper barrel 16 has an opening 60 receiving one end of a box 61 the opposite end of which communicates with the interior of the :fan housing 62. Numeral 63 represents the fan housing outlet.

A valve 6 1 is for the purpose of closing up the passage through theup-t-ake pipe or conduit and of opening an exhaustpassage 65, leading from a locomotive fire box and through the exhauster, when-the motor 59 is operated to actuate said exhauster, the

, said valve 64 being adapted to open up the passage throughsaid up-ta'ke pipe or con duit and to close said exhaustpassage when said exhauster is not functioning. As disclosed, the vajlve 64 is pivoted in the barrel 16 at a location intermediate the ends of said valve, as indicated at, 66, andincludes an arm 67 for closing the passage through the barrel 16 and an arm 68 for closing passage through the box 61., one of said arms being in open position while the other .arm is in closed position. The arm68 is constructed to be heavier than the arm 67,

so that normally the passage through-the box 61 is closed; and passage through the barrel. 16 is open. The arrangement isjsuch, however, that when the fan 58 is operated,

.suction created in the'box 61 is sufficient to draw the arm .68 to about the position as disclosed in Fig. 2, to thus open the passage through said box and close passage-through the barrel '16, as will be obvious.

Supposing the bar 40 to be in normal position, say, for example, as disclosed in dotted lines in Fig. l, and it is desired to associate a locomotive smoke stack with the mouth 42 of theup-take pipe or conduit 15,

allthat is necessary to be donegto accom of several difler'ent positions to, provide a smoke-tight association between said stack and theiupetake pipe or .conduit, as will be ment as disclosed obviously makes provision understood. After the smoke stack has associated itself with the mouth of the up-take pipe or conduit, movement of said smoke stack still farther ahead will obviously cause the barrel 21 and the bar 40 to be still farther elevated and said bar 40 to be slid longitudinally ahead. Upon return movement of the locomotive, the smoke stack will not be removed from the up-take pipe or conduit until the rearward position at which the smoke stack entered the barrel 21 has been passed, so that a locomotive can be moved forwardly and backwardly within limits while associated with the uptake pipe of the apparatus without permitting smoke or gases to be emitted into a round-house.

The utilization of raising and lowering mechanism actuated by the smoke stack of a locomotive to associate the up-take pipe with, and to disassociate said up-take pipe from, said smoke stack, eliminates all labor and maintenance which have heretofore been 'disassociation of stacks with apparatuses of the present character, and the arrange-- for variations in the heights of locomotive smokestacks, as well as for variations from the vertical as may be caused by broken springs.

As will be evident, whenever the bar 40 and the barrel 21 are elevated by a smoke stack,jthe cover 53 will be in open position, and when said bar and barrel are allowed to lower, said cover will be closed.
